Check Digit Verification of cas no

The CAS Registry Mumber 1201664-50-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,6,6 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1201664-50:
(9*1)+(8*2)+(7*0)+(6*1)+(5*6)+(4*6)+(3*4)+(2*5)+(1*0)=107
107 % 10 = 7
So 1201664-50-7 is a valid CAS Registry Number.

Catalytic Generation of Donor-Acceptor Cyclopropanes under N-Heterocyclic Carbene Activation and their Stereoselective Reaction with Alkylideneoxindoles

Prieto, Liher,Sánchez-Díez, Eduardo,Uria, Uxue,Reyes, Efraím,Carrillo, Luisa,Vicario, Jose L.

, p. 1678 - 1683 (2017/05/22)

Formylcyclopropanes undergo activation in the presence of an N-heterocyclic carbene catalyst generating a donor-acceptor cyclopropane intermediate with the ability to undergo ring-opening followed by formal [4+2] cycloaddition with alkylideneoxindoles. This enables the direct enantio- and diastereoselective synthesis of tetrahydropyrano[2,3-b]indoles through the use of a chiral NHC catalyst. (Figure presented.).
